If you want larger scale Grey Aliens in 25/28mm scale , check out ZombiesSmith, Griffin Miniatures, 3D-Miniatures, Wargames Supply Dump and Brigade Games. ZombiesSmith Greys are chalk full of character. 3-D Miniatures and Griffin Miniature Greys are very alien like. Brigade Games are more realistic, but still have a ton of character. Wargames Supply Dumps are not exactly Greys, but they have a ton of character and are close enough.
